Heisenberg Uncertainty Players

**Heisenberg Uncertainty Players** is a Chicago-area jazz big band formed in 2011 by founder and music director **John Dorhauer**, specializing in original compositions and arrangements that blend funk, Latin jazz, hip-hop, classical, swing, and even pop covers like "I Want It That Way." This 17- to 18-piece ensemble pushes beyond traditional big band sounds, treating the group like a personalized orchestra with a focus on color, texture, and long-form development—think epic tracks like those on their albums *Return to the Enchanted Forest*, *Gradient*, *Catalpa*, and *Emergency Postcards*.

Over the years, they've built a strong rep in the Windy City scene with more than 200 performances, thematic concerts tackling everything from boy bands and heavy metal to NBA-inspired suites like *The Basketball Suite* and tributes to demolished baseball stadiums in *We Tear Down Our Coliseums*. Supported by Illinois Arts Council grants and spots at festivals like Ear Taxi, the band's top-notch musicians deliver precise, sensitive playing that feels huge yet intimate, making each release—like their latest adventures in enchanted forests and gradients—a fresh, immersive listen.
